The very simple intro.  The timing can be figured out from the song.

e[-----------------]
B[-----------------]
G[-----------------]
D[-----------------]2x
A[---5----5---3-2--]
E[-3----3---3-3-3--]

This is what's played during the song itself, with the little 3-note addition in-
between the segments.
